Iminostilbene carbonyl chloride resolve resolution
Two molecules of o-nitrotoluene are condensed with the participation of sodium methoxide to produce 2,2′-dinitrobiphenyl, and then reduced with iron powder-hydrochloric acid to obtain 2,2′-diaminobibenzyl.
The latter phosphate is cyclized under heating conditions to obtain 10,11-dihydro-5H-dibenzo[b,f]aza, which is then chloroformylated with phosgene, and finally brominated and eliminated ( Debromide) to obtain the product.
